Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed November 6. 1907. Serial No. 400.944.

To all whom it may concern:

Be it known that I, THOMAS J. 000, subject of the King of England, and resident of Toronto, Province of Ontario, in the county of York and Dominion of Canada,

have invented certain new and useful IInprovements in Type-Writing Machines, of which the followin .is a s'pecification.-

My invention re ates to typewriting ma chines and more (particularly to bearings for.

the type bars, an ithas for its object to provide an improved roller bearing for the type bars.

hereinafter appear, my invention consists of the features of construction,- arrangements of parts and combinations of devices to be hereinafter set forth and particularly pointed out in the appended claims.

is received. These arms are perforate In the accompanyin drawin s, Figure 1 is an enlar ed sectional view ta on through the axis 0 the type bar and showing t e means for mounting the type baron its hanger. Fig. 2 is an enlarged longitudinal sectional view of the same taken on the line m-o: of Fig. 1 and lookin vin the directionofthe arrow at said line. ig. 3 is an enlarged side view of a roller separator employed in A type bar 1 isiprovided with an eye 2 formed with an internal V-shaped race-way having bearing walls 3 and 3 for coopera tion with crossed anti-friction'circularly arranged bearing rollers 4 and 4. The typebar hanger 5 may be formed as shown n Fig. 1 and' is bifurcated to provide hanger arms 6 between which the eye of the t' e bar fFtO receive' a screw 7 whichjpasses between and connects the arms and is threaded at one end for cooperation with one of theopenings in the arm, which opening is tapped to receive the screw. The opening in the other arm of the hanger is countersunk to receive the head 8 of the screw.

A bearing cone' 9 base central opening To the above and other ends which willtherethrough in order that the cone may be supported on the screw 7 between the arms of t e hanger as shown in Fig. 1, The cone 9 is provided witha projection or stem 10 threaded for coiiperation with a central tapped opening in acompanion .bearing,

cone 11. The cone 9 is supported upon the screw 7 between the ha er arms and the cone '11 is supported on t e cone 9, the hanger arms hearing at opposite sides on the cones to. maintain them m their adjusted position with relationto each other. A

roller separator 12, shown in detail in Fig. 3,

has a central 0 ening 13 to receive the stem 10 of the bearing cone 'sothat said stem constitutes a support on which the roller separator ma turn with the bearing rollers aperturesbeing shown in the present instance. Each of these a ertures receives an anti-friction bearing r0 er 4 or 4 and. the-separator is contained between the bearing cones 9 and 11 and is limited in its axial ,movementby said cones. I The bearing roll-. ers 4 and 4 are circularly arranged and the.

axes of revolution of alternating rollers extend at angles .to each other and the axis of each roller extends at an angle 'to the axis Either or f of revolution of .the type bar. both of the cones 9 and ll maybe provided with screw-driver nicks 15 whereby a,rela

he roller separator is formed with apertures 14 in the edge thereof, six

tive axial adjustment between the cones in parallel planes may be efiected. When the cones have been properly adjusted for cooperation with the crossed bearing rollers 4 and 4" the screw 8 may be tightenedin order inorder to retain them against relative rotation and to hold themin the position to which thiy have been adjusted' rom an ins (action of seen that the roll the type bar. unite the right of the typebar as shown by 'thevdotted line a, have their peripheries cooperating with the cone 11. and with the bearing wall 3 formed by the-V- shaped bearing cave in the surroundin eye 2 of the type ar so as to receiver. latera or axial thrust of the t e bar in but one direction; and that the ends of said rollers do not receive a bearing or supporting contact against the cone 9 or the bearing wall 3 f of the type bar. On' the other hand, the

- to force the hanger arms 6 against the cones Fig." 1 it will be ers4,.the axes of which extendinzo'ne direction, towards the axis a of.

89 I each'other and -at their ends on the cone 11 and the bearing "rollerfbearing .in'

said parts" afvting jrollers-extending atangles to each other an to the axis of revolution ofthe type'bar, 40- tween certainof'said bearings. I '3. Thejcb mbination of a type bar, ahanger, m

one of said'fgparts and a 'bearin other rollers" 4 tending to the left of the ty e bar and towards the axis thereof as indicated by the dotted line I), hear at their peripheries on the cone 9 and the wall 3 in v the eye of the type bar so as to receive the lateral or axial thrust of the type bar in anopposite direction. The rollers d do not receive-a supporting bearing wall 3* in the eye of thetype bar. In other words, the. rollers 4 which have their axes extending in one direction as indicated by the dotted line a form abearing. support for the type bar only at the eripheries thereof, whereas the bearing rol er's-4 which have their axes extending in the op osite direc-' tion as indicated bythe'dotted line I) also form a bearing onlyat the peripheriesthere-- lateral thrust of of, the rollers receiving a the type bar in one direction and the rollers 4* receiving a lateral thrust of the type bar in the op osite direction. x x I What; claim as new and desire to secure by Letters Patent, is:

1. The combination of a type bar ,a hanger, one of said parts having an eyefwith. a roller bearing inf-the eye and the other of said parts havin a bearing, and bearing rollers between t e bearings, the axes, of' alternating rollers extending at angles to to the axis of revolution of thetype bar.

"Z. The combination of a bifurcated hanger, relatively adjustable bearin cones supported by said hanger between t e arms thereof,

a type bar having a rounds said cones, tained within said eye and between said cones, and rollers 'contained betweenthe cones and bearin eye' and cooperative with said separator, t e axes of certain of said rellers-extending'at angles to the axes of certain other ofsaid rollers. i
